ARMOR FCR PNEUMATIC TIRES.

SPECIFICATION forming part of Letters Patent No. 723,299, dated March 24, 1903. Application tiled December 1'7, 1902. Serial No. 135,544. (No modela To a/ZZ whom t may concern:

Be it knownthat I, HARRY PARSONS, engineer, a subjectof the King of Great Britain and Ireland, residing at 67 Beechdale road,

BrixtonHill, Londom England, have invent-` ed a certain new and useful Improved Antislipping and Antipuncturing Device for the Tires of Vehicles and for Like Purposes, of which the followingr is a specification.

Hitherto it has been proposed to guard against slipping and puncturing `by incorporating an antislipping or antipuncturing device in the tire itself, which has the effect of slowing it considerably or causing disintegration and having other objectionable features. According to my invention I overcome these objections by providing a separate construction, giving, in elect, a non-slipping medium between the surfaces in contact and merely suspended on or engaging with the wheel, but not fixed thereto, and it is therefore free to travel around the wheel by the action of rolling contact. i

The device constituting myinvention consists of a network of 4rings or strips of metal or other .suitable material or a series of small chains or bands fitting loosely over the periphery of the wheeler passing from lside to side across the tire-thatis, not incorporated with it-and prevented from coming oft by two rings, hoops, or their equivalent, preferably of wire or other suitable material, such rings or the like, or one of them, being provided, if desired, with means of attachment and detachment, such as a right and left hand screW-threadand nut, and the said rings or the like being smaller in diameter than the periphery of the wheel they cannot come oft" accidentally. In the event of a nail or other puncturing instrument entering a pneumatic tire when the device is applied thereto the net or chains or the like in their movement over the tire will withdraw thesaid nail orf the like, while the rough surface provided by the network, chains, `or the like willprevent slipping of the tire on the road. y

The device is applicable not only to the wheels of vehicles;` such as cycles and motorcars, but also to a `number of analogous purposes, such as the prevention of belt-slip on pulleys, the increase ofgrip on friction-rollers, and similar cases. 1

I show in Figures l and 2 of the accompanying drawings the pneumatic tire of a motor road-vehicle, for example, to which a device according to my invention is applied, Fig. l being an end elevation and Fig. 2 a side elevation. Fig. 3 shows an arrangement by means of which either or both of the rings ot' the device can be adjusted.

ot is the pneumatic `tire of a wheel, and b represents two rings of wire,\(or wire rope or the like,) one ou each side. To these rings are secured, by brani-ng or otherwise, lengths of chain c, which pass diagonally across the tire, as shown, so that the chains and rings of Wire together form a kind of iiexible trough, which extends over the periphery of thetire and is prevented from becoming detached from the wheel by reason of the wires b beiug of less diameter than theouter circumference of the tire, while the device is otherwise not attached to the wheel. As the wheel (in the case of the application of the device to a road-vehicle) revolves on the road the chains b afford a perfect grip on the road, which While it prevents slipping does not impede the movement of the wheel.

I do not limit myself to any particular construction of chain, and although I have mentioned chains I do not limit myself to the use of chains, as they may be replaced by any other suitable arrangement of any suitable material which will give the requisite grip and iiexibility, such as a series of interlaced rings like those of torpedo-nets, say, extending over the mid-part of the circumference of the tire and attached to rings, such as b, by short lengths of diagonal chains or the like.

Either or both ot the rings b may be provided with ends reversely screwed into a correspondingly right and left handedscrewnut d, Fig. 3, with its exterior' formed to receive an instrument for tightening up and IOO Y certained the nature of the said invention and in what manner the same is to be performed, I declare that what I claim isp 1. Antislipping or protecting means for the peripheries of wheels, pulleys or the like, comprising attaching elements at opposite sides of the wheel,and au antislippingorprotective medium secured to the attaching elements and extending across and around the periphery of the wheel, said parts being disconnected from though retained on the wheel whereby the antislipping or protective medium is free to move or shift its position around the periphery thereof.

2. Antislip'ping or protecting means for the peri pheries of wheels, pulleys or the like, comprising attaching elements at opposite sides of the wheel and a iiexible antislipping or protective medium secured to the attaching elements and extending across, around and bearing upon the periphery of the wheel, said parts being disconnected from though retained on `the wheel whereby the antislipping or protective medium is free to move or shift its position around the peripheryT thereof.

3. Antislipping or protective means for the peripheries of wheels, pulleys or the like, coml prising attaching elements at opposite sides of the wheels of less diameter than the peripheral diameter of the wheel, and an antislipping or protective medium secured to the attaching elements and extending across and around the periphery of the wheel, said parts being disconnected from but retained on the wheel whereby the antislipping or protective medium is free to move or shift its position around the periphery thereof.

4. Antislipping or protective means for the peripheries of wheels, pulleys or the like, comprising two rings or annuli at opposite sides of the 'wheel and an antislipping or protective medium secured to the rings and extending across and around the periphery of the wheel, said parts being disconnected from but retained on the wheel whereby the antislipping or protective medium is free to move or shift its position around the periphery thereof.

5. Antislipping or protective means for the peripheries of wheels, pulleys or the like, comprising two rings or annuli at opposite sides of the wheel and of smaller diameter than the same, one of the rings having jointed ends which may be separated to expand the ring to slip it over the wheel,and an antislipping or protective medium secured to the rings and extending across and around the periphery of the wheel, said parts being disconnected from but retained on the wheel whereby the antislipping or protective medium is free to move or shift its position around the periphery thereof.

6. Antislipping or protective means for the peripheries of wheels, pulleys or the like, comprising two rings or annuli at opposite sides of the wheel, and an antislipping or protective medium consisting of a chain or chains secured to the rings and extending across and around the periphery of the wheel, said parts being disconnected from but retained on the wheel whereby the antislipping or protective medium is free to move or shift its position around the periphery there'of.

In testimony whereof I affix my signature inl presence oftwo witnesses.

HARRY PARSONS.
